I'd go with just don't send dick pics to anyone...

Yup because 9 out of 10 times, if someone is asking for one, it’s not to screw you in the way that you want.

sure that wont backfire if reported

OP and the girl would of started talking, sjed ask him to add her on Facebook and then she'd go "if I send a nude, do you want to send me a dick pick" and then she'd go "if you don't give me X amount of money, I'll send the dick pic to everyone on your Facebook account."

That's what I was thinking. We are not sure how long they have been talking or if she asked for it. Either way, won't it be revenge porn?

Not necessarily. There are protections in place for people who do revenge porn. The person with the picture could be charged.

Who said it was unsolicited.

Noone said they think he just sent it without being asked. She probably asked for it for the purpose of extorting money from him. That doesn't make it any less stupid. You just shouldn't send things like that to people you just recently met on the internet. Some might argue you should never, but certainly not to some random person from an app.

Several people used the word “unsolicited.”

The story does not say he'd sent it at all. Who says it's his dick pic?

Why would you pay $100 to prevent the revealing of a rando dick?

Maybe it’s an embarrassingly small dick, and he doesn’t want his friends to think it’s his?

Well, if you never include your face and genitalia on the same picture, nothing can really happen.
